Objective: Each group should use our shared Narrow River Data Set to teach us something interesting.
assign roles in your group: 2 people should analyze data, 1 person should do background research and 1 person should write the conclusion.
use a graph as evidence for your claims.
Question: What causes the big jump in conductivity?
Group Members: Katie McAuley, Sarah Rockwell Chris M, Kerry K
Background Research
pH is a measure of the hydrogen ions within a solution.
Conductivity is a measurement of all ions present. A high concentration of ions is a high conductivity. However, if the ions form compounds the conductivity measurement decreases.
Why is this question interesting?
This question is interesting because each site has different results for this measurement. We want to determine if there is a corrolation between the different measurements.
We can observe through our graph that these two values are unrelated. This is supported by our background information that we collected. Although both values are measurements of ion concentration, pH only measures the concentration of hydrogen ions and does not take into account the ions from salts within a solution. Hydrogen ion concentration behaves independantly from other salts and is thus unrelated to conductivity. The two values are unrelated.
